BOX-BOARD-IPEEPARING MACHINE.

Application filed January 20, 1926.

This invention relatesto a machine for preparing a sheet or blank ofbox-board for bending into box form, by forming lines of Weakness in theblank, and thus adapting the blank to be bent along predetermined lines.In some cases the lines of weakness are elongated cuts or incisionsformed in one end of the blank by the annular cutting edge of an.indenting disk of the scoring type, the other side of the blank beingsupported by a rotating bed roll fixed to a driven shaft. In othercases, the lines of weakness are elongated creases formed by thecooperation, with a peripherally grooved bed roll on the driven shaft,of an indenting disk of the creasing type, adapted to groove the blankwithout cutting it.

The invention is embodied in an improved bed roll or collar, soconstructed that a plurality of like collars may be adjustably securedto a single driven shaft and cooperate either with scoring disks, orwith creasing disks, with which the machine is provided, theconstruction of the collars being such that they are capable of a widerange of adjustment on the shaft, permitting adjacent collars to belocated practically in contact with each other on the shaft, to form thelines of weakness at a minimum distance apart, and more or less widelyseparated from each other on the shaft, to form the lines of weakness atvarious distances apart.

Of the accompanying drawings forming a part of this specification,

Figure 1 shows in perspective the body portion of a bed collar embodyingthe invention.

Figure 2 shows in perspective one of the rings hereinafter described,forming parts of the collar.

Figure 3 is a fragmentary view, showing in section a collar embodyingthe invention, and in elevation a portion of the driven shaft to whichthe collar is secured, a creas ing disk being shown in position tocooperate with a peripheral portion of the collar in creasing a blank.

Figure 4 is a View similar to Figure 3, showing a scoring disk inposition to cooperate with another peripheral portion of the collar inscoring a blank.

Figures 5, 6 and 7 are fragmentary views similar to Figures 3 and fl,and on a smaller scale, showing a plurality cutters, and

denting disks, and different adjustments thereof.

Figure 8 is a fragmentary sectional view, similar to a portion of Figure3, showing a modification.

The same reference characters indicate the same parts in all of thefigures.

In the drawings, 1.2 designates a shaft con-- stituting an element of abox-board preparing machine. The shaft may be supported in any suitablebearings, and driven by any suitable means. The machine may includeindenting disks 13, of the creasing type, and indenting disks 14 of thescoring type, said disks being loosely rotatable in suitable supports,and arranged to cooperate with the hereinafter described bed collarssupported and driven by the shaft 12.

The indenting disks may be supported by means shown by the RobinsonPatent, No. 273,394c, dated March. 6, 1883, said means permittingvarious adjustments of the disks.

The shaft 1.2 is arranged to support the bed collars in operativerelation to the disks. I provide a plurality of bed collars supported bythe shaft 12, and adjustable thereon to conform to adjustments of theindenting disks. Each collar has a grooved peripheral portion or zone16, adapted to cooperate with a creasing disk, as indicated by Figure 3,and a plain peripheral portion or zone 17, adapted to cooperate with ascoring disk 14, as indicated by Figure 1.

Each collar has a hub portion 18, embrac ing the shaft 12, and movableendwise there on. The hub portion preferably projects from one side ofthe collar, and is provided with a securing member, such as a set screwv 19, whereby it may be detachably secured to the shaft. The oppositeside of the collar is provided with a recess 20 formed to receive theprojecting hub portion of another collar, so that two adjacent collarsmay be located in close proximity to each other, as shown by Figure 6,thus reducing to a minimum the distance between two creases formed bythe cooperation of two similarl adjusted creasing disks 13, with groovedperipheral portions 16 of the two bed collars. The distance between thecreases may be increased more or lessby adjustments of the bed collarsseparating the collars from each other, the creasing disks beingcorrespc'rnd lVhen it is desired to score instead of crease, the bedcollars and the scoring disks Ll are adjusted to cause the cooperationof the scoring disks 14 with the plain peripheral portions 17, indicatedby Figure 7.

Each bed collar is preferably composed of an annular body portion orsection 22, integral with the hub portion 18, and two rings 23,detachably secured by screws 24- to opposite sides of the body portion.The plain periphery or none 17 is formed on the body portion, and theperiphery of each ring 23 forms a grooved zone 16.

If desired, the scoring disks 1 1- may be adj usted inward, by meansshown by the Robinson patent, so that they will cooperate with the plainperipheral zones 17 in entirely sev ering instead of scoring, themachine being thus adapted to cut a sheet of boxboard into strips, inwhich case, the creasingdisks 13 may be removed from their operative position by means shown by the Robinson patent.

It will now be seen that a machine organized as described may be readilyadapted to crease, score or cut, and that a quick change from a creasingadaptation to a scoring or cutting adaptation is permitted.

\Vhen the machine is adapted for creasin creased boxes may be made ofminimum size, and considerably smaller than any heretofore made. so faras I am aware.

Instead of providing. the collar with a pcripheral creasing; zone whichis grooved, and the corresponding. creasing disk 13, with a peripheralrib, I may reverse the arrangement and provide the collar with aperipheralcreasing zone which includes a peripheral rib 16 formed tocooperate with a creasing disk 13,. having a peripheral groove 13 asindicated by Figure 8.

The peripheral creasing zones 16 or 16 of the collars are formed ondetachably secured rings 23, to enable the said Zones to be removed anddifferently formed Zones substituted therefor. Said rings are preferablysplit or divided into sections, as indicated at 25 a (Figure 2), so thata ring may be applied to and removed from a collar without removing thecollar from the shaft 12.

I employ two rings in each collar, to provide a wider range ofadjustment, and to hold a ring in reserve, so that in case of damage toone rin zof a collar, the other ring may be substituted therefor.
